6214 Deep Groove Ball Bearing | Open, ZZ, 2RS High-Speed Bearings
The 6214 deep groove ball bearing is a high-spec heavy-duty model in the 6200 series, featuring upgraded rolling element configuration and thickened raceway structure for greater load capacity and mechanical stability. This single-row deep groove ball bearing delivers excellent radial and axial bearing performance, outstanding anti-fatigue strength and consistent dimensional accuracy during long-term high-speed and heavy-cycle operation. Optimized for medium to heavy industrial equipment, the 6214 bearing offers low-friction, low-noise and long-lifespan rotation. It is available in three standard versions: open type, 6214ZZ double metal shield type and 6214-2RS double rubber sealed type, with five industrial-grade material options to adapt to economic, sanitary, high-wear and corrosive working environments.
6214 Open / ZZ / 2RS Structural Features
6214 Open Type: The unsealed open structure provides unrestricted airflow and efficient heat dissipation, effectively preventing thermal overload during continuous high-speed operation. It supports easy grease refilling and routine cleaning without increasing rotational resistance. Suitable for clean, dry indoor workshops and fully enclosed precision machinery, it maintains stable running accuracy and reliable performance under long-cycle heavy-load conditions.
6214ZZ Double Metal Shields: Equipped with dual-sided non-contact steel shields, this dust-proof bearing effectively blocks fine dry dust, floating particles and micro workshop debris. The non-contact design retains original high-speed precision and smooth rotation with minimal friction loss. Featuring excellent durability and cost performance, the 6214ZZ is widely used in dry automated production lines, industrial heavy-duty motors, power transmission systems and general electromechanical equipment.
6214-2RS Double Rubber Seals: This fully sealed variant adopts double-sided contact rubber seals for comprehensive protection against moisture, splash water, oil mist and corrosive dust. It securely locks internal lubricating grease to prevent leakage and aging, enabling long-term maintenance-free operation. It is ideal for humid, dusty, splash-prone and outdoor industrial working scenarios.
6214 Bearing Material Performance
Carbon Steel: Standard cost-effective industrial material with uniform hardness and stable anti-fatigue properties. It delivers reliable wear resistance and smooth high-speed rotation for heavy-load machinery, offering excellent cost performance for mass industrial and civilian applications.
304 Stainless Steel: Food-grade stainless steel with superior oxidation and rust resistance. It maintains precision stability in humid and open environments, suitable for food processing equipment, light industry and daily precision mechanical devices.
316 Stainless Steel: Premium marine-grade corrosion-resistant material with strong acid, alkali and salt spray tolerance. It withstands chemical erosion and coastal high humidity, perfect for sanitary equipment, marine auxiliary machinery and chemical precision instruments.
420 Stainless Steel: High-toughness martensitic stainless steel combining moderate corrosion resistance and high surface hardness. It provides excellent wear and impact resistance, ensuring stable dimensional accuracy during long-cycle heavy-load operation.
440 Stainless Steel: Ultra-high hardness stainless steel with top-tier abrasion resistance and structural stability. It sustains precise operation under severe wear and corrosive conditions, ideal for high-end industrial heavy-duty precision equipment.
Core Advantages And Industrial Applications
The 6214 deep groove ball bearing features outstanding heavy-load capacity, high structural rigidity, ultra-low noise and durable high-speed performance. Three diversified sealing structures and five professional material grades fully cover economical, anti-rust, wear-resistant and anti-corrosion industrial scenarios. It is extensively applied in heavy-duty industrial motors, automated transmission systems, large mechanical equipment, precision instruments, food processing machinery, medical devices and outdoor industrial facilities, providing stable, low-maintenance and high-efficiency precision rotation solutions for modern medium-heavy duty mechanical systems.
